I still remember my middle school life in Zhengzhou. I was then in school for student from Tibet. As we were all left home of an early age, we met lots of problems in our daily life. We had to do the washing, cleaning and shopping by us. However, we seldom felt lonely or helplessly. We enjoyed our happy life. At weekends, we will play basketball on the playground, swimming in the pool or go for a picnic in the park. We were living in a big family. We treat each other as brothers and sisters. It has been three years when we graduated, but those memories are as sweet as ever before.
